Towards an extensible measurement of metadata quality

Abstract

This paper describes the structure of an extensible metadata quality assessment framework, which supports multiple metadata schemas, and is flexible enough to work with new schemas. The software has to be scalable to be able to process huge amount of metadata records within a reasonable time. Fundamental requirements that need to be considered during the design of such a software are i) the abstraction of the metadata schema (in the context of the measurement process), ii) how to address distinct parts within metadata records, iii) the workflow of the measurement, iv) a common and powerful interface for the individual metrics, and v) interoperability with Java and REST APIs.
